Virtual Image Migration

The virtual appliance supports direct importation of application data from older Tenable Appliance VM disks. The process for importation involves adding the previous appliance's disk files to the new appliance as a third and fourth drive.

  • Prior to performing the migration it is recommended to make a backup of the current VM. This helps to ensure a way to recover if there is an issue during the migration process.
  • Depending on the amount of data currently on the VM, the migration process may take several hours to complete due to database import and rebuild time.
  • This process only migrates data for the Tenable applications that were previously installed. Settings from the previous Appliance are not migrated.
  • Due to differences in VMware products, platforms, and versions, the steps described here are written for general use. The specific wording of options varies depending on the software being used.
  1. Shut down your current version or higher Tenable Appliance VM.
  2. Edit the settings for the current version of Tenable Appliance within your VMware management software. Under the “Hardware” section, begin the process to add another hard disk. Choose to use an existing virtual disk and select the *-disk1.vmdk then *-disk2.vmdk files in that order from your existing Appliance. If asked, choose to keep the existing format of your .vmdk files.

    When selecting the second .vmdk file, note that you must again browse to the directory containing your previous disk files. The VMware software does not open for browsing in the previously used directory.

  3. Once the disk addition is complete, start your Tenable Appliance image. Use your web browser to navigate to your Tenable Appliance web interface.

    Some versions of VMware may display a message warning against using a duplicate UUID. Select the “Yes” button and continue to start the VM.

    Use your web browser to navigate to your Tenable Appliance web interface.

  4. At the top of the Admin page a "Tenable Application Data Import" section will be displayed.

  5. When the “Import Application Data” button is clicked, it will perform the import of data in the background.
  6. Once the page reloads, the “Import Application Data” button will be replaced with text indicating that the import process is in progress. The System Log contains progress messages and includes a final “Application Data Migration Finished” message.
  7. Once the migration is complete, shut down the Tenable Appliance. Edit your VM and go to the “Hardware” section to remove the Appliance .vmdk disks added in step 2.
  8. After removing the hard disks, boot the updated version of Tenable Appliance. You may log into your applications and find your previous data is now available.
